NEW PUBLICATIONS. 



The Primary Factors of Organic Evolution. — E. H. 

 Cope, Ph.D. Chicag-o: The Open Court Publishing- Co. 

 In publishing- this neat octavo volume of over 500 pp.. Dr. 

 Cope has made quite a valuable addition to the literature 

 pertaining- to the problem of evolution of the animal king-- 

 dom. The book is divided into three parts, showing- the 

 nature of variation, causes of variation and "The Inheri- 

 tance of Variation." The deductions made are carefully 

 drawn and broug-ht to a final conclusion with infinite ex- 

 actness. Over 100 illustrations embellish the work. 



The Bacillus of Chancroid. — Colombini has been work- 

 ing- on this subject, and publishes his results in a pamph- 

 let. He finds that the bacillus of Ducrey and the strepto- 

 bacillus of Unna are one and the same org-anism, charac- 

 terized by being found in chains, by staining- chiefly at the 

 ends and not in the centre, by being- decorlorized by Gram's 

 or Kuhne's method, by the difficulty of obtaining- pure 

 culture since a suitable nutritive medium could not be 

 found, and by the rounded ends of the individual bacilli. 

 The best staining- ag-ent was methelene blue. Inoculation 

 into animals was uniformly neg-ative. The bacillus is 

 rarely found in bubonic pus. 



Defective Sanitation in Italy. — According- to Professor 

 Bodio, of 8,254 communities in Italy, 1,454 have no supply 

 of pure water, and 4,877 no reg-ular sewag-e system.
